(cits-131) Claims.

This invention relates to forms for concrete walls and particularly to sheet metal wall forms.

An object of the invention is to provide a form for a concrete wall minimizing the embedding of tie or spacer members in the formed wall.

Another object is to provide a concrete wall form comprising spaced panels held upright and in proper opposed relation by stanchions engaging. or definitely spaced from the outer faces of such panels.

Other objects are to mount said stanchions on elongated forms for a wall footing, to adapt such footing forms to definitely anchor the stanchions in proper positions, to adapt the stanchions to interconnect aligned units of the footing forms in abutting relation, and to provide simple devices for quickly securing the panels toor releasing themfrom the stanchions.

A further object is to provide an improved means for forming. window or other openings in a monolithic concrete Wall, and to provide an adjustment for such means adapting it .to various Widths of openings.

A further object is to connect stanchions at opposite sides of the wall by suitable tie mem bers, and to adapt the latter to various spaced A relations of the stanchions.

A further object is to provide a concrete wall form having a provision for forming a wall with a ledge for seating floor joists or a facing of brick or the like, or for reducing a wall thickness at 7 a certain .level for any desired purpose.

These and various other objects are attained by'the construction hereinafter described and il- 'lustrated in the accompanying drawings, wherein:

Fig. 19 is a, perspective view of a panel-supporting wire bracket.

Fig. 20- is a vertical sectional view, taken on the line 20-2fl of Fig. 18, showing said bracket in use.

In these views, the reference characters A and B designate spaced inner and outer wall-forming panels, each comprising a plurality of similar rectangular panel plates Labutting each-other end to end, and superposed one on another to estab- 11811 a desired length and height for the panels. Welded or otherwise rigidly secured to the exterior face of each panel plate is an angle bar reinforcement 2, bordering and substantially flush with the periphery of the plate. Also rigidly carried by each plate I on its exterior face is a pair of horizontally elongated U-shaped reinforcing bars 3 spaced from each other and from the top and bottom edges of the plate.

The panels A and B are held upright and in definite spaced relation by stanchions 4 disposed in exterior proximity thereto, and seating at their lower ends on inner and outer horizontally elongated sheet metal footing form 5, which also carry the panels. Such forms are suitably spaced apart, each comprising a suitable number of units arranged in end-to-end relation, two thereof being shown in Fig. 1. Each footing form unit comprises a vertical Web member 6, a coextensive shelf member I inwardly projecting from the member 6 at the top of the latter, and a trough-shaped member 8 substantially coextensive with the member 6 and exteriorly extending along the base thereof. Each shelf member I is formed at its inner edge with an upturned flange Ia, against which the superposed panel plate I abuts, said flange assuring a proper spacing and.

parallelism of the lower panel plates, provided that the footing forms are parallel. At the ends of each units, flanges 9 project above the ends 'of'the trough member 8, converging toward each other.

Sheet metal spacer plates ID are employed to establish and maintain the proper relation of the-inner and outer footing forms 5, said plates extending transversely beneath and forming supports for such forms. Such plates are reinforced at their longitudinal margins by upturned flanges II and their ends are similarly reinforced by flanges I2. As best appears in Fig. 4, the flanges 'I I are terminally spaced from the flanges I2 forming gaps I3 into which the trough members 8 of the footing forms may fit to properly space the inner and outer forms. The end portions of each spacer plate rigidly carry a pair of upstanding sheet metal channels I4 which fit beneath and support the shelf members I of the footing forms,asFig.2 discloses. Said spacer plates are preferably located at the junctures of the footing form units, as per Fig. 1.

The stanchions 4 each comprise a pair of opposed channel-shaped sills" I5, and a series of vertically spaced connections I6 between such sills, said connections being each reinforced by an upturned inner marginal flange I1 and a downturned outer flange I8. Further connectionsbetween said sills are formed by a cap piece I 9"at the top of each" stanchion and an extension 20' carried by theba s'e portion of each stanchion upon'its'outer face, such extension projecting exteriorly adjacent to the web 6 of the form underlying the stanchion and fitting into the trough member'B ofsuch' form to resist such outward thrust as is exerted on the stanchion in use. Each extension 20 is preferably centrally upwardly slitted'from its lower edge, as indicated at 2 I, sothat in locating the stanchions at the junctures of aligned footing form units, the slits 2I may engage abutting, divergent flanges 9 of the units, so that the stanchions interconnect the unit's'in their abutting relation and are anchored in place by said flanges. (See Figs; and 6.)

It is often desirable to reduce the width of a "concrete wall at a certain height,an objective of sucha reduction frequently being the formation of a ledge to seat joists or a facing tier of brick or other units. The present invention effects a reduction of wall width, with resultant formation of a ledge, by offsetting one of the panels A and B'toward the other at the desired height, the offset being formed by a course of relatively narrow horizontally disposed panel plates 22, the outer edges of which surmount'a course of the panel plates I and the innerv margins of which carry the upward continuation of the offset panel. The

plates 22 are reinforced by up-standing flanges 23 set back from the longitudinal edges of such plates and serving also to properly position the plates I adjacent to the inner margins of the plates 22. To hold the plates 22 rigidly in place on the underlying course of panel plates, there is employed a plurality of approximately U-shaped spring clamps 24 formed preferably of sheet metal, said clamps embracing the lapped outer margins of the members 22 and top flanges of the plates I. Such clamps are also preferably used at various other points to assure firm engagement, as for example to embrace the abutting flanges of adjoined panel plates. (See Fig. l.)

The panel plates which lie against the stanchions are firmly secured to the latter by small sheet metal latch plates 25 which are centrally upwardly slotted as indicated at 26 and thus adapted to straddle abutting flanges of the channel bars 3 and connections I6. Elongated sheet metal latch plates 21 each having two upwardly extending slots 28 interconnect the outer stanchions with those panel plates I which are inwardly spaced from said stanchions, said p ates having each'of their end portions formed with one of the slots 28, the inner slots receiving channel flanges on the panel plates and the outer slots receiving flanges H of connections I6. Similar latch plates preferably releasably connect the horizontal plates 22 to the stanchions, as appears in Fig. 1.

Inner and outer stanchions 4 are oppositely disposed and connected at their upper ends by spacer bars 29 formed preferably of two spaced elongated angle bars rigidly connected at their ends by similar angle bars. The elongated angle bars have vertical flanges adapted to straddle the stanchions and horizontal flanges which seat on the caps I9 of the stanchions. Pins 30 are transversely mounted in'the end portions of said bars to engage the outer faces of the connected stanchions, and latch elements 3I, formed of heavy wire, have terminal eyelets which slip over the pins 30 to pivot said elements, the other ends of the latter being hooked to engage inner edges of the stanchion sills. Preferably a plurality of apertures 32 are formed in the end portions of the bars 29 to permit such adjustment of the pins :30 as will accommodate them to various spaced relations of inner and outer stanchions. Spacing of the latter is determined by the thickness of the wall to be formed. In addition to exercise of their spacer function, the bars 29 may serve to carry a plank runway (not shown) for wheel- 'barrows employed in' delivering cement to the wall form.

In producing window or other openings, in use of the described form, a pair of angle brackets comprising vertical plates 33 and horizontal plates 34, carried at the lower ends of the vertical plates; aremounted between the panels A and B in a spaced relation determined by the desired width of opening. The plates 33 are reinforced at their upper margins by flanges 35 having terminal extensions beyond said plates to seat on the top edges of a course of the plates I. The opposed faces of the plates 33 and top faces of the plates 34 are reinforced by flanges 36. Connect ing the plates 34 is an extensible member comprising a pair of overlapping plates 31 to vary the joint length thereof. The member comprised by the plates 31 is bolted to and between the plates 34, as indicated at' II.

At the corners of a wall to be formed, one of the relatively transverse outer footing form units "said units.

42 which further serves to interlock the two units. The fitting 42 is bent to-form' end portions *43 and 44 which fit into the troughs 8 of the two footing units and is slitted upwardly as indicated at 45 to accommodate the flanges! of Atits upper margin, the fitting is formed with a reinforcing flange 46. (See Figs. 12 and 13.)

Inner footing form units in meeting at a wall "corner are interlocked, as shown in Fig. 14, by

a sheet metal fitting i! of box shape. Said fitting fits into the trough portions 8 of the meeting units and is upwardly slit as indicated at 48 tostraddle the abutting flanges 9 of the units. The slit as is formed at one of the vertical edges of said fitting, which has its diagonally opposite edge portion split from top to bottom to form portions to fit within troughs 8. The upper end 'of the fitting is partially closed for reinforcing purposes as indicated at 49.

Figs. 16, 17 and 18 show the form as extended up from any floor 58 of a building. In such floor,

in these holes, serving to hold in place the inner panel B, seating upon and rising from said floor.

The outer panel A is held in place by a suitable number of stanchions which are seated upon beams ie, similar in all respects to the stanchions abut disposed horizontally adjacent to the outer face of the wall 52 which underlies the floor 50,

and is to be now upwardly extended. The beams 4a are arranged with their ends formed by the extensions 20 hearing against said wall, as best appears in Fig. 16, the other ends of such beams overlapping the eXtensions 2B of aligned adjoining beams 4a. Thus the extensions 20 on the beams so space the beams outwardly from the wall as to form an elongated space suited to accommodate the extensions 20 of the stanchions seating on said beams. To hold the beams 4a in place, bolts 53 engaging said beams, are extended through the wall 52, and. preferably through window or door openings 54 in such wall, to engage anchorage bars 55 engaging the inner face of such wall. Thus the panels A and B may be erected on successively higher floors of a building to permit extending the latter to any desired height. After thus forming a wall rising from any floor, as 56, the holes of such floor may be readily eliminated by filling the same with concrete.

When it is desired to support a panel without using either the footing forms or the floors as a support, there is employed a suitable number of such brackets 53 as are shown in Figs. 19 and 20. Each of these brackets comprises a length of wire bent to U-shape, and further bent at its closed end so that, in resting on one of the connectors it, it may be hooked to engage beneath the flange E8 of said connector, while its parallel ends seat on and project beyond the flange 51. Thus said projecting ends may serve as a panel support as clearly appears in Fig. 20. This is particularly useful in extending the outer panel upwardly above any floor of a building, as in Fig, 18.

The described form may be quickly set up or taken down and is of such durable construction that it may be used a great many times without material deterioration. Since the plates 5 are the only elements of the form to become permanently embedded in the concrete wall, these are the only parts requiring replacement after each use of the form.
